hone

hone is a skill for Claude Code from acostanzo/quickstop. It costs 17 tokens per session (3,091 once invoked), scanned A, original, MIT.

A five-phase audit procedure for checking and improving an existing Quickstop plugin against the Claude Code plugin specification. Quickstop is a plugin marketplace and development toolkit.

In plain words
What is it for?
Running `/hone` on a named plugin, discovering its files, checking metadata and layout, researching hooks and MCP configuration, and producing an audit with improvement guidance.
Why use it?
It turns plugin review into a repeatable process that checks the plugin exists, inventories its files, researches relevant rules, and identifies quality issues. It prevents structural or configuration problems from being overlooked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hone scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hone: Plugin Quality Auditor

You are the Hone orchestrator. When the user runs /hone <plugin-name>, execute this 5-phase audit workflow. Follow each phase in order. Do not skip phases.

Phase 0: Discovery

Step 1: Parse Plugin Name

Extract the plugin name from $ARGUMENTS. If empty or missing, list available plugins by globbing plugins/*/ and use AskUserQuestion to ask which to audit.

Step 2: Validate Plugin Exists

Glob for plugins/$ARGUMENTS/.claude-plugin/plugin.json. If not found, tell the user the plugin doesn't exist and abort.

Step 3: Build Plugin Manifest

Run parallel Glob calls to discover all files under plugins/<name>/:

Category Glob Pattern
Metadata plugins/<name>/.claude-plugin/*.json
Skills plugins/<name>/skills/*/SKILL.md
Skill references plugins/<name>/skills/*/references/*.md
Agents plugins/<name>/agents/*.md
Hooks plugins/<name>/hooks/*.json
MCP plugins/<name>/.mcp.json
Docs plugins/<name>/README.md
Legacy plugins/<name>/commands/*.md
All files plugins/<name>/**/*

Get line counts for all discovered files via a single Bash call: wc -l <file1> <file2> ...

Step 4: Present Plugin Map

=== PLUGIN MAP ===
Plugin: <name> v<version>

Skills (N):
  skills/<skill>/SKILL.md              XX lines
  skills/<skill>/references/foo.md     XX lines

Legacy:

Total: N files, ~N lines
=== END MAP ===

Tell the user:

Phase 1: Building expert context from official plugin documentation...

Phase 1: Build Expert Context

Step 1: Load Expert Context

Invoke /claudit:knowledge ecosystem to retrieve ecosystem knowledge.

If the skill runs successfully (outputs === CLAUDIT KNOWLEDGE: ecosystem === block):

  • Use its output as the ecosystem portion of Expert Context
  • Also read .claude/skills/smith/references/plugin-spec.md for plugin-authoring-specific detail (plugin.json schema, directory conventions) that the ecosystem cache may not cover at full depth
  • Combine both as Expert Context
  • Skip to Phase 2

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
